In an embodiment as illustrated in FIG. 2, mounting assemblies 30, 30′ are secured inside the vehicle. In some embodiments, mounting assemblies 30, 30′ are secured to inside surfaces such as walls of the vehicle or a gun turret of the vehicle. FIG. 2 illustrates an embodiment of soldier platform system 5 having mounting assemblies 30, 30′ on opposing sides of seat 20. In embodiments as illustrated in FIG. 2, one mounting assembly 30 has an attached release assembly 35. The attached release assembly 35 is attached to a strap 40 that attaches mounting assembly 30 to seat 20. Strap 40 may be secured to seat 20 by any suitable means. In an embodiment as illustrated, strap 40 is secured to seat 20 by strap attachment means 50. Strap attachment means 50 includes any means suitable for attaching a strap to a seat. In an embodiment as shown, strap attachment means 50 is a bracket that swivels. Without limitation, a bracket that swivels allows limited motion of seat 20. In some embodiments, strap 40 includes adjusting means 80. Adjusting means 80 is any means suitable for adjusting the length of strap 40 between release assembly 35 and seat 20. The other mounting assembly 30′ has an attached mounting strap 45 with a release assembly 35 attached on the opposing end of mounting strap 45 from mounting assembly 30′. In some embodiments, mounting strap 45 includes adjusting means 80. Seat 20 is attached to mounting assembly 30′ by a strap 40 that attaches the release assembly 35 to seat 20. FIG. 2 illustrates an embodiment that has two mounting assemblies 30, 30′ but it is to be understood that soldier platform system 5 is not limited to two mounting assemblies 30, 30′ but in alternative embodiments (not illustrated) may have more than two mounting assemblies. Mounting assemblies 30, 30′ are secured in the vehicle at a sufficient height to suspend seat 20 at a desirable height in the vehicle (i.e., from the floor or a platform in the vehicle). Adjusting means 80 allow the length of straps 40, 45 to be adjusted to adjust the suspension height of seat 20. Straps 40 attach seat 20 to release assemblies 35 by attachment means 85. Attachment means 85 may include any suitable means for attaching a strap to an object such as a hook, bracket, latch, and the like. Straps 40, 45 have a sufficient tension to facilitate suspension of seat 20 but in some embodiments also have a sufficient tension to allow the individual to have a desirable amount of movement while secured in seat 20. For instance, in an embodiment in which soldier platform system 5 is secured in the vehicle to allow the individual to sit in a gun turret of the vehicle, the soldier may have a desire to move about in the interior when operating a weapon in a combat situation or to view outside the vehicle. Mounting assemblies 30, 30′ may be secured in the vehicle at any degrees apart to provide a seat 20 of sufficient stability to allow an individual to sit in seat 20.

FIGS. 1 and 2 illustrate an embodiment of soldier platform system 5 in which one mounting assembly 30 has a release assembly 35 attached to the mounting assembly 30, and the other mounting assembly 30′ has a release assembly 35 attached with a mounting strap 45 attached in between the mounting assembly 30′ and the release assembly 35. Without limitation, the mounting assembly 30 has the release assembly 35 attached to provide a release assembly 35 at a sufficient proximity to the individual sitting in seat 20 to allow the individual to pull the release assembly 35 and quickly drop seat 20. Further, without limitation, the mounting assembly 30′ has the release assembly 35 at a lower position in relation to seat 20 to provide a release assembly 35 at a sufficient proximity to other individuals in the vehicle to pull the release assembly 35 and quickly drop seat 20. For instance, soldier platform system 5 may be mounted in a gun turret of the vehicle wherein the soldier secured in soldier platform system 5 has the upper portion of the soldier's body exposed outside of the vehicle. In a combat situation, the soldier secured in soldier platform system 5 may desire to quickly drop down in the vehicle for protection by the vehicle. In such a situation, the release assembly 35 attached to mounting assembly 30 provides a convenient release assembly 35 by which the soldier may pull and release seat 20, thereby allowing the soldier to drop into the vehicle for protection. The soldier may also pull the release assembly 35 attached to the mounting assembly 30′ with the mounting strap 45 in between, but, with seat 20 in an elevated position allowing the soldier to be positioned in the gun turret, the position of such release assembly 35 provides a convenient release for other soldiers in the vehicle to pull and release seat 20 to allow the soldier to drop into the vehicle for protection. For instance, the soldier may be injured and unable to pull a release strap 135, and such lower positioned release strap 135 allows the other soldiers to pull the release strap 135 and thereby allow the injured soldier to be quickly protected inside the vehicle. It is to be understood that soldier platform system 5 is not limited to release assembly 35 attached to one mounting assembly 30 and another release assembly 35 disposed at a lower position in relation to seat 20. Soldier platform system 5 may have release assemblies 35 disposed at any position in relation to seat 20. In an alternative embodiment (not illustrated), a mounting assembly 30 and/or 30′ may have one release assembly 35 attached to the respective mounting assembly and at least one other release assembly 35 disposed between the one release assembly 35 and seat 20. In other alternative embodiments (not illustrated), both mounting assemblies 30, 30′ have a release assembly 35 attached to the respective mounting assembly 30, 30′. In some alternative embodiments (not illustrated), both mounting assemblies 30, 30′ have an attached release assembly 35 with a mounting strap 45 disposed between the respective mounting assembly and the release assembly 35. It is to be understood that when one release assembly 35 is pulled to release seat 20 from the respective mounting assembly 30 or 30′, seat 20 remains secured to the other mounting assembly 30 or 30′, which protects the individual secured in soldier platform system 5 in the event of a roll over or injury from other motion of the vehicle.

In operation of the embodiments of ratchet platform 70 illustrated in FIGS. 1 and 13-25, ratchet platform 70 is placed in a vehicle (not illustrated). Ratchet platform 70 is secured in a desirable location within the vehicle. Ratchet platform 70 may be secured by any suitable method such as by screwing ratchet platform 70 to a floor or other surface of the vehicle. The vehicle may include any vehicle such as a truck, car, military vehicle, helicopter, air plane, and the like. In an embodiment, ratchet platform 70 is placed in a military vehicle in which it is desired for an individual to stand on platform 415. For instance, in some military vehicles, it is desired for an individual to operate weaponry (i.e., machine gun) that is located on the outside of the vehicle. In such an embodiment, a portion of the individual's body is disposed outside of the vehicle during operation of the weaponry with the remainder of the individual's body within the military vehicle for protection. The height of platform 415 is adjusted by pressing pedal 555. Each time pedal 555 is pressed, the pressure from pedal 555 actuates pedal linkage 565 and pedal linkage 565 moves upwards, which thereby actuates upper linkage 515 longitudinally upward. The longitudinal movement of upper linkage 515 slides ratchet pin 520 longitudinally upward through the length of actuator groove 550. The upward movement of ratchet pin 520 applies force to a tooth 350 of ratchet rail 445 thereby actuating platform upper assembly 240, which moves upward. Pressure is released from pedal 555, and torsion spring 535 applies force to pedal linkage 565 to actuate pedal linkage 565 and move pedal linkage 565 downward, which actuates upper linkage 515 to move longitudinally downward. Such downward movement of upper linkage 515 slides ratchet pin 520 downward through the length of actuator groove 550 to allow the tooth 350 below the previous tooth 350 (in which the force was applied) to be disposed upon ratchet pin 520. By such disposition of the next tooth 350 upon ratchet pin 520, further downward movement of platform upper assembly 240 is prevented. Pedal 555 may be pressed and released until platform 415 is at the desired height. To reduce the height of platform 415, pedal 555 is pressed and held, which maintains ratchet pin 520 in an upper position within actuator groove 550. With ratchet pin 520 maintained in an upper position within actuator groove 550, ratchet pin 520 is not in contact with teeth 350, and platform upper assembly 240 slides downward until the pressure is released from pedal 555 or support column 390 contacts platform 415. As platform upper assembly 240 slides downward, platform riser tube 440 slides downward in interior 330.
